Marijuana is pure evil, according to Drug Enforcement Administration (DEA) Administrator Michele Leonhart. Speaking during an official congressional testimony to Rep. Jared Polis (D-Colo.), Leonhart told Congress that "all illegal drugs in Schedule I are addictive" and constantly repeated that "all illegal drugs are bad."

There's just one problem: legalizing medicual marijuana will have the exact opposite consequence on America. Need proof? There are 22 diseases that can be effectively treated using cannabis. That's right, 22.

22. Bipolar disorder: This study found that bipolar subjects with a history of cannabis use had better neurocognitive function than those with no history of cannabis use.

Sorry, Leonhart, you're just wrong: Medical marijauna is on an unstoppable upswing in the U.S. Support is coming from both sides of the aisle, the FDA is close to making major moves towards making it a legal pharmaceutical and more and more states are considering, or already making, the push towards legalizing medical marijuana. Twenty-three states now allow medical marijuana use, and 11 others have limited allowances for CBD (one of the therapeutic compounds in the plant).

If there's any doubt as to whether legalizing will have a positive impact, let the list above be the judge.
